name	castcodes-plugin-host
description	Work on CastCodes plugin host, skill, MCP, CLI-agent plugin manager, native or WASM plugin host, app plugin, and plugin-related command behavior. Use when editing plugin support or adding plugin-facing capability while preserving the public OSS hosted-service boundary.

Workflow

Use this skill for plugin-host and plugin-facing work in the app. Read references/plugin-map.md when ownership is unclear.

Before editing:

1. Identify whether the change is in the native/WASM plugin host, app plugin service, terminal CLI-agent plugin manager, MCP settings, bundled skills, or command exposure.
2. Confirm whether the change requires the plugin_host Cargo feature.
3. Check whether the plugin path can reach hosted auth, MCP OAuth, cloud agents, shared sessions, or upstream service URLs. If yes, use castcodes-fork-local-boundary.
4. Keep plugin behavior local and explicit in public OSS builds unless CastCodes-owned infrastructure is configured.

Implementation Rules

• Preserve existing plugin host module boundaries under app/src/plugin/**.
• Keep CLI-agent plugin manager behavior scoped to the provider manager being edited.
• Do not add marketplace or install metadata for repo-local skills unless the user explicitly asks for plugin packaging.
• Do not make plugin discovery depend on upstream hosted services in the public OSS path.
• For plugin commands that appear in UI, verify command palette and slash-command availability matches actual runtime support.
• For MCP OAuth or cloud-backed plugin behavior, require explicit unavailable or disabled OSS behavior.

Verification

Run focused tests for the edited module when present. At minimum for app plugin-host code:

cargo check -p warp --bin cast-codes --features gui,plugin_host

If the change touches public identity or hosted services, also run:

./script/check_rebrand
cargo test -p warp_core --features local_fs castcodes

If plugin_host is not needed for the touched path, explain why the normal gui check is sufficient.

Related Skills

• Use castcodes-fork-local-boundary for hosted service or MCP OAuth exposure.
• Use castcodes-ui-work for plugin commands, settings, or command-palette surfaces.
• Use castcodes-dev-loop for broader verification command selection.
